This invention relates te improvements in duel Wheel :monntings and itconsists oi the 'matters hereinefter described end more perticulerlypointed ont in the appended cleims.

The primary object of the invention is to provide n novel ond improvedmounting for the wheel members of e duel wheel upon the associated bnbof e motor vehicle .snob es e truck, bus or other lieevy duty vehicle ofthis Mind, "wherein e resilient driving engagement or connection is hadbetween the adjacent ports of the Wheel members and between one of seidWheel members end the hub back dongle, 'tlins reducing the shearingtendency on the nsnel wheel attaching bolts toe minimum,

A further object of tbe invention is to provide such e mounting whereinno direct engagement is hed between the "wheel members themselves orbetween each of seid `Whee1 members end the lnlb beck ilenge, so thetthere is no transmission of noise between the severel ports, whereby equiet running wheel structure of this lrin'd is produced.

Iiliese objects of tire inventiones well es others, tooether with tberneny advantages thereof will more nlly eppear es proceed with myspecioetion.

Referring nov:r in detail to that erobernrient of tile inventionillustrated in Fig, l of the drevyin; 1 indicetes es e whole, the iinbborrel oi e nonl duty rector veliiclea having e redini beclr gringo 2 tovthe roer side of which the iront nell 3 of e brake drum l is :Ixed bythe rivets d shown in Fig. l.

The duel or double wheel of such e vehicle is indicated es e, Whole et 5end comprises inner end outer spaced Wheel members 6 nd 7 respectively,each carrying e rim 8 adept:- ebie to receive e pneumatic tire indicatedet As shown herein each 'Wheel member consists of e wheel disc l0 hevinge dat central portion 1l of e diameter approximating tirato-f the backdonga end en outer annu# ler band portion 12 to support the associatedrim 8. Said Wheel portions lle-11 ooohl beve e central hole to loosely tupon the inib barrel so es to be centralized with res 'spect thereto.Eecii disc is inclined with re spoot toits exis and when the wheelmembers erein operative position upon e, hub, lliey are opposed to eecb.other so es to space the associated rims end 'tires eport to preventengagement end abrasion between seid tires.

The central portions of both Wheel bodies lieve a plurality ofregistering holes 13e-i3 therein, which holes also register withthreaded holes 14 in the beck ilange and iront Well of the broke drum..Associated with eeenI .set of holes 13-13 end 11i is e bolt l5 andthese bolts ere adapted 'to secure the Wheel bodies to the hub but erenot relied n Jon es the solo means *for providing the driving connectionbetween the wheels end hub. To provide such e driving connection .lemploy'rnembers 16 end 17 respectively which ere to e certain extent comressibie, between the inner "Wheel body en beck enge end also betweenthe inner and outerl wheel bodies. -As shown in Fi l these members erediscs'or rings of resllien-t materiel provided with suitable holesregistering Witn the holes i3 end 14 or the bolts i5. When seid boltsere drawn up tight the disc 16 gives e Lilill ieee resilient drivingcontect,or engsgement,-'between the back flange and inner Wheel body andthe disc i7 gives e nll'iece resilient driving contact or engagementbetween the inner end coter wheel bodies; seid discs removing thedrivino strain trom the bolts. Again such discs being compressed to someextent, prevent the entr-ence of water between the yvvbeels end bocknnge so that no rusting tney take piece end seid discs else ect toabsorb such sounds or noise is produced When the vlieel os e y whole istravelling over rough or uneven roadways.

As before mentioned the bodies of the wheels shown in Fi 1 are of thedisc type and such-a bod is i ustrated in elevation in Fig. 2 or the odymay have openings 10'* therein to simulate spokes 10b and such a body isshown in Fi 3. This last mentioned type of wheel body 1s advantageous inthat it permits ventilation through the wheel to dissipate the heatgenerated in the brake drum when the brakes are actuated at`comparatively short intervals as when employed in passenger busses.Again the inner wheel may be of the form shown in Fig. 3 and the guterwheel may be of the form shown in In Fi 4 is illustrated a slightlymodified.l form o wheel construction wherein .the central portion 20-20of the wheel bodies 21-21 about the hub barrel hole are depressedannularly as at 22-22 on the bolt circle and these parts are faced awayfrom each other. In this instance I provide two driving rings 23--24 ofsuch cross sectional contour as-to snugly fit against adjacent wheelbody and back flange parts and a convexed ring 25 is employed inconnection with the portion- 22 of the outer wheel body through whichthe attaching bolts 26 ass. In said ring about each bolt opening 1s anoutwardly extending boss 27 to provide a seat for the head of the bol-t.When said bolt is drawn up tight to provide that engaement between thevback flange, wheel o ies and friction rings necessary for the resilientdrive between said parts the ring 25 also acts in the fashion of a cupwasher to prevent loosening of said bolts.

In Fig. 5 is shown a further modified form of wheel wherein the centralportions' of the wheel bodies 21"--21'l are providefdi':

with a plurality of inwardly and opposed apertured embossments 20-2()ELand with resilient driving rings 23-24", the rin between the inner wheelbody and brake rum wall and back. flange being of a diameter greaterthan that of the other ring. In this case as before the bolt 26* passesthrough the several parts and a cup washer 25n is interposed between thehead of lthe bolt and the embossments in the outer wheel bod lIn all ofthe constructions describe a clearance is left between the shank of thebolt and `rwheel bodies and resilient rings so that said bolts in no waact as drivers except in their function` o drawing the parte together inthat relation required to give the resilient driving connection betweenthe parts described. In this manner much labor and material are saved ina wheel structure and the annoyance of sheared or otherwise damagedbolts is eliminated as well as the noie such as is found in dual wheelsas now ma e.

While in describing my invention I have referred in detail to the formand arrangement of the parts thereof, the same is to be considered as byway of illustration only so that I do not wish to be limited theretoexcept asmay be pointed out in the appended claims.

I claim asmy invention 1; A dual wheel construction embodying therein ahub having a back flange, a plurality of wheel bodies mounted on thehub, one adjacent the back flange and means providing a'resilient drivebetween said wheel bodies and between one of said wheel bodies and theback flange.'

2. A dual wheel construction embodying therein a. hub having a backflange, 'a plu- :rality of wheel bodies, mounted on the hub, oneadjacent the back flange, resilient driving means between said wheelbodies and means rfor securing said wheel body adjacent the back flangeto the same.

3. A dual wheel construction embodying therein a hub having a backflange, a plurali-ty of wheel bodiesmounted on the hub, one adjacent theback flange, resilient driving means between the wheel bodies andbetween said back flange and the wheel body adjacent the same and meansfor securing said parts together.

4. A dual wheel construction embodying therein a hub having a backflange, inner and outer wheel bodies, spaced from each other and withthe inner body spaced from the back flange, a resilient driving memberinterposed between the central portions of the wheel bodies, a secondresilient driving memberbetween the central portion of the inner wheelbody and the back flange and means for demountably securing the wheelbodies upon the hub.

In testimony whereof, I have hereunto set my hand, this 1st day of Setember, 1927. Y
